I had started on something similar for 1020, but put it on hold due to imxrt-rs/imxrt-ral#32.
Have you already written a consumer for the flexio::Pin trait? My hunch is that having const OFFSET: u32 rather than type Pin: consts::Unsigned is easier to work with. It also has precedence in gpio::Pin.

Have you already written a consumer for the flexio::Pin trait?

Will give it a try within the next days.

[Finomnis]

@Florob I didn't get to writing a consumer yet, but in theory I agree, so I changed it.

Is this what you had in mind?

Actually not. I was talking about the Pin associated type, not the generic.
I'd try to align with the gpio::Pin trait here, which has the generic as consts::Unsigned, and then an OFFSET: u32 associated constant.

I'm uncertain what you mean. imxrt_iomux::gpio::Pin has a const N: u8 generic.

I adjusted it a little, is it better now?

@Florob I'm not far yet, so far I only print the parameters, but this is the driver I'm working on: https://github.com/Finomnis/ws2812-flexio
Just for information.

I'm so sorry. I must somehow have been looking at an ancient revision. What you have now is indeed what I would have suggested.

That link 404s for me. Is the repository set to private perhaps?

[Finomnis]

@Florob Oops. Fixed. Apologies.

Thanks for reviewing the interface. I'll release in v0.2.
